安裝PyQt5
pip install PyQt5 -i https://pypi.douban.com/simple
安裝QTdesigner
pip install PyQt5-tools -i https://pypi.douban.com/simple
打開QTdesigner
我的位於下面的目錄
D:\Anaconda3\Lib\site-packages\pyqt5_tools\Qt\bin\designer.exe
如果報錯
需要將
D:\Anaconda3\Lib\site-packages\PyQt5\Qt\plugins\platforms
復制到
D:\Anaconda3\Lib\site-packages\pyqt5_tools\Qt\bin\platforms
就ok了
Ubuntu特殊情況
如果報錯
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.
Aborted (core dumped)
需要終端加入
export QT_DEBUG_PLUGINS=1
再運行程序進行調試
查看輸出的結果。
解決方案
sudo apt install --reinstall libxcb-xinerama0
可能用到的
sudo ln -sf /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/ /usr/bin/
sudo apt-get install qt5-default qttools5-dev-tools
sudo apt-get install python3-pyqt5
sudo apt-get install libx11-dev libxext-dev libxtst-dev
sudo apt-get install xlibmesa-gl-dev libglu1-mesa-dev
sudo ln -sf /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/ /usr/bin/
sudo apt-get install libcap2-bin
設計界面
設計完成后，保存為.ui文件
在終端中輸入命令
pyuic5 .\untitled.ui -o none2.py(pyuic5.bat在conda庫中存在)
修改py文件
文件上部加入
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QMainWindow, QWidget, QApplication
import sys
下部加入
if __name__ == "__main__":
app = QApplication(sys.argv)
mainWindow = QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(mainWindow)
mainWindow.show()
sys.exit(app.exec_())
展示一下結果
